Excessive smoke with wmo

[edub32]

I'm running about a 85% wmo (5 micron) diesel right now and for some reason lately ive been starting to get a lot of blue smoke. at 65 in OD it seems to clear up but at starting and medium speeds theres quite a bit. should i premix before pouring into tank or am i running to "rich" of a mixture.

i pre mix. it could be that you are running to high of oil mix. try going to a 50% WMO or 25%.

what is the highest % you guys use without any smoke?

Sounds like you are running too thick a mix. I have run 100% wmo with no more noticeable smoke but the ambient temp was high. Meaning it was hot outside.
I now run in the 80 to 85% range. Is your source actually wmo or some blend of that? Sometimes people get a blend of used oils with different weights and i have noticed a difference there.
I run a heat exchanger so it affects me a little less than most. And I test my mix with a hydrometer so that its near or the same as #2. Bio-Diesel: Farm Grown Profit will help you with that.

How do you get WMO to be the same specific gravity as diesel fuel? The WMO is a thicker, heavier oil and I don't see any way around that except for heating or thinning.

edub32, in my IDI, it will smoke alot at idle with a 50% WMO/50% #2 blend. I'm now running 66% oil and I try not to let it idle too long to avoid smoking people out and building up deposits on the pistons/valves/etc. As far as I can tell it doesn't smoke any when running at road speed.

I run 2thirds diesel 1 third oil in a four cylinder Ford trader and have a slight smoke at wide open throttle [most of the time] as it is loaded all the time.
Tried heavier concentration of oil that smoked and at idle would run a oily deposit out the exhaust[short and no baffles].
Hot motor=better burn.

Indeed. Mine is definitely happier now that I covered part of the radiator and the engine maintains 195-200*F. I think part of the equation is the water temp where the coolant comes back into the engine, if that is too cold then part of the cylinders will be too cold. I'm kicking around putting a temperature gauge in the water inlet, and covering/uncovering my radiator to maintain 120-130 inlet temps.

I have a 2000 i have been up to about an 85% to 90% oil and have noticed that with hydraulic fluid there is more smoke at medium speeds and idle than used engine oil. Temps. have also cooled down which play a big factor in the smoke. getting on it hard a few times to clear it all helps out some when getting into cities where i feel bad.

I run 50/50 mix. I mix first then filter down to 2 microns. Mine smokes at idle. The longer it idles the more it smokes. Once moving there is no smoke. Of course if you get on it or pulling hard it will smoke like on regular diesel.

Am I the only one that doesn't care about smoke?

I run 90% or so, if it is warm out, I run basically 100%. This winter I guess I have to step it down to 50%. I don't care about the smoke.


Should I care??

What you do is your business. Me personally, I feel self conscious when i'm next to someone in traffic and filling their cabin with the acrid smoke and carcinogens.

The hardcore environmentalists might give you a hard time, call the police/etc.

I have thought about it when I drive off next to a bunch of people standing on the corner or something. I also try not to line up next to people's open wndows if possible, but the usually roll their window up just because of my engine noise anyhow.

My cover story if a cop stops me for smoke is that "I've been having problems recently."

The 'smoke' is unburnt fuel and soot. If ya think that its not leaving deposits in your combustion chamber, you are really, really naive.

Beyond that, it stinks and increases dangerous toxins in the air we all have to breathe. Listen, diesel fumes are bad enough in a truck that runs RIGHT - w/no smoke.

I could give a sh!t that you are destroying a perfectly good truck, maybe its not worth much to you - but our kids and grandkids will spend their lifetimes trying to undo what the industrial revolution did to our environment. Why do you think we have 'clean diesels' now? The PSD cut emissions like 90% over the original IDI engines - why go back in time?

Look, I am not a 'tree-hugger', per se - but I recognize the fact our air IS cleaner than it ever was in my lifetime. Luckily, like the dinosaurs and the huge, polluting cars of the 60 & 70's - the 'old geezers' whose belief that the earth is too big and resilient for us to damage are dying off, albeit slowly...

Like I always say, y'all choose wisely or PLEASE, PLEASE post pics of the carnage!!

[edub32]

Hmm I love how you post worthless information on everyones wmo and wvo mix threads. I'm asking for help not your criticism. I believe someone posted on here their emissions test with wmo and it ran cleaner then #2.

[airfooter]

You are correct, my appologies. The truth is, you are at least a little uncomfortable with your decisions, or ya wouldn't have posted what you did. I know my 'information' is useless to those who have already made up their minds, but my hopes are only to save those for whom it is not too late.

I hear horror stories all the time lately about folks having major engine problems from running 'blends' of WMO and WVO. It seems most folks aren't as 'lucky' as yourself and the others here that tout WMO as a great fuel alternative. (are ya still lucky, my smokey friend?) Of the 1000's who read these threads, how many post? Right.... of the rest, how many 'try it'? So add to that it may take ya 20-30k miles to fubar your engine or take out that 1rst set of injectors (tip of the iceberg, btw) - and you've really had some impact!

Saving the world always has been a thankless job! (gimme a break! like I take myself even a fraction that seriously!)

Thats why I always say choose wisely or post the carnage!

FWIW, I promise not to muddy up another one of yer threads - for awhile... and as always my friend, the beers are all on me, cheers!
